Abstract:A novel flow injection microfluidic immunoassay system for continuous monitoring of saxitoxin, a lethal biotoxin, in seawater samples is presented in this article. The system consists of a preimmobilized G protein immunoaffinity column connected in line with a lab-on-chip setup. The detection of saxitoxin in seawater was carried out in two steps: an offline incubation step (competition reaction) performed between the analyte of interest (saxitoxin or Ag, as standard or seawater sample) and a tracer (an enzyme-… Show more
“…As a result, the diffusivity of bare SPEs and PET_SPEs comparable to the one reported in the literature by Konopka and McDuffie was assessed. 24 Analogously, a similar planar diffusion-controlled process in the oxidation/reduction reactions of the selected redox probe was found for Bio-SPEs and Bio-PET_SPEs. Subsequently, I pa and I pc were plotted as a function of the scan rate ( γ 0.5 ).…”
Flexible screen-printing technology modified with nano/material coating boosted the manufacturing of highly sensitive electrochemical sensors for fast and easy-to-handle tests in different application fields.
